Background:
Lasers are advantageous in some applications to stimulate a small target area and is used in various fields such as optogenetic, photoimmunological and neurophysiological studies.
Objective:
This study aims to implement a non-contact sense of touch without damaging biological tissues using laser.
Methods:
Various laser parameters were utilized in safety range to induce a sense of touch and investigate the human responses. With heat distribution simulation, the amount of changes in the temperature and the tendency in laser parameters of sensory stimulation were analyzed.
Results:
The results showed the identified tactile responses in safety range with various laser parameters and temperature distribution for the laser stimulus was obtained through the simulation.
Conclusions:
This study can be applied to the areas of sensory receptor stimulation, neurophysiology and clinical medicine.
